Application filed November to, 1901. Serial No. 404,664.

To all whom it may concern:

Be it known that I, IRVIN SOHUCKMAN, a citizen of the United States, residing at Gar- 1 den City, in the county of Finney and State of Kansas, have invented a new and useful Beet-Cultivator, of which the following is a specification.

This invention has relation to beet cultival tors and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to rovid'c a cultivator of the character indicate wnich is plants simultaneously and which is provided with a simple and effective means for steering the im lement along the rows of lants.

Wit the above object in view t e machine caster wheels and a foot lever mechanism 0 eratively connected with the spindles of t e casters of said wheels for turning the same. A pair of beams is journaled in the frame and each beam is rovided with ground engaging members. eans is provided for turning the said beams axially whereby the ground engaging members mav be elevated with relation to the ground ant means is also provided for liberating the spindle of the rear caster wheel when the said beams are turned whereby the implement may be readily turned around at the end of the row. Means is provided for moving the ground engaging members into engagement with the ground which means is operated directly from the draft of the draft animals attached to the igure 1 is a top plan view of the beet cultivator. Fig. 2 is a side elevation of the same showing the standards in one position. Fig. 3 is a side elevation of the same with parts in section showing the standardsin another position, and Fig. 4 is a detall side elevation of the upper portion of one of the caster spindles used on the cultivator.

The implement consists of the frame 1 which is sup orted at its forward end by the caster whee s 2 and at its rear end by the caster wheel 3. The forward corners of the which are'journaled the spindles 5 of the casters carrying the wheels 2. A lever mechanism 6 is provided for shifting the spindlcs 5 longitudinally with relation to the sleeves 4 whereby the forward end of the frame 1 may be readily adjusted with rcln tion to the surface of the ground. The rear end of the frame 1 is provided with a vertically disposed sleeve 7 in which the spindle 8iof the caster of the wheel 3 is journaled and in which the said'spindle may move longitudinally. The pulley 9 is mounted upon the sleeve 7 and the eye 10 is mounted upon the collar 14. The cable 11 passes under the pulley 9 and attaches with the e e 10 at its rear end. The forward end of t e cable '11 is attached to the lever 12 which is fulcrumed upon the frame 1.

The upper end of the spindle 8 is provided with an arm 13 which is provided with a collar 14 which receives the spindle 8. The said collar is provided in-its upper side with a recess 15 which is adapted to receive the pins 16 mounted upon the-spindle 8. The eye 10 is attached to the collar 14 and coil s ring 17 is interposed between the upper en of the sleeve 7 and the lower side of the collar 14 and is under tension to hold the recess 15 in engagement with the pin 16. The trip lever 18 is fulcrumed on the frame 1 in advance of the operator's seat 19. ally attached at its forward end to the lever 18 and at its rear end to the arm 13. The upper end of each of the spindles 5 is provi ed with an arm 21. The link 22 is pivotally connected at its forward end to one of the arms 21 and at its rear end to the lever 18 at substantially the same point of connection'therewith as that between the link 20 and the said lever. The forward end of the link 23 is pivotally connected to the other arm 21 and its rear end is pivotally connected to the lever 18 upon the opposite side of the fulcrum point thereof from the point of connection between the link 22 and said lever. The beams 24 and 25 are journnlcd in the bearings 26 and 27 respectively, )rovided in the depending brackets 27 of the lrmnc 1. Said beams are arallel to each other and are connected toget er at their outer ends by the links 28. The lever 12 is mounted upon'the beam 25 and carries a spring actuated pawl 29 which engages the gear segment 30 attached to the frame 1. The ground engaging mcmbers 33 are attached to the beam 24 while the ground engaging members 34 are attached to the'beam 25. The beams 24 and 25 are also provided with the de ending arms 35 to which are pivotally attac ed the rear end portions of the draft rods 36. The forward ends of the-said draft rods are pivotalLy connected tothe superstructure. 37

The link 20 is pivothis feet which throu h the links 20, 22 and mals operating through the shafts 38, struc ture 37 and draft rods 36 will pull the arms loosening the caster at therear end of the which, in turn, is attached to .the shafts 38 1' or a tongue corresponding to said shafts.

The operation of the implement is as follows: As it is drawn along the rows of plants the operator manipulates the lever 18 with 23 and the attache arms turn the caster spindles 5 and 8 axially which swings the wheels 2 and 3 whereby the implement may be propel-l directed with relation to the standing p ants. When the row is reached the lever 12 is swung forward which turns the beams 24 and 25 axially. Thus, the ground en aging members 33 and 34 are swung to t e rear and elevated out of the ground. At the same time the forward movement of the lever 12-draws upon the cable 11 and the eye 10 located upon the collar 14 is drawn toward the eye 9. Thus, the recess .15 is disengaged from the pin 16 and the spindle 8 is free to turn irres ective of the lever 18 and its connection. hus by frame 1 and at the ends of the rows the machine may be readily turned to pass back across the field. When the machine assumes its proper alinement with relation to a new set of rows the lever 12 is swung to the rear when the coil spring 17 will cause the recess 15 of the collar 14 to receive the pin 16 and at the same time the strain of the draft ani- 35 positively toward the front which will cause the shafts 25 and 24 to rotate axially whereby their respective ground engaging members will be forced into the ground.

Having described my invention what I claim as new and desire to secure by Letters- Patent is 1. In a device of the ldnd described, a 1

frame supported on a trinity of caster wheels, steering elements for simultaneously and e ually changing the angular relation of said wheels to the frame, digging members mounted adjustably for height on said frame, and means to simultaneously lift said digging members and release one of said wheels from its steering element.

2. In a device of the kind described, a frame sup orted on a forward pair of casterwheels and a single rear caster wheel, steering elements for simultaneously and e ually changing the angular relation of al said wheels to the frame, means for independently adjusting the height of the two front wheels, digging members mountedadjustably for height on said frame, and means to simultaneously lift said digging members and release the rear wheels from said steering elements.

3. In a device of the kind described, a

frame, supported on a trinity of caster wheels, steering elements for simultaneously and e ually changing the angular relation of said w eels to the frame, a clutch arranged to releasably connect one.of said wheels to the steering elements, digging members mounted adjustably for height on said frame, and a latch leverconnected to said digging members and the clutch arranged to slmultaneously lift the diggin members, release the clutch, and free sai wheel from said steering elements.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature 1n the presence of two witnesses.

IRVIN SCHUOKMAN.
